Warn user when they insert simple comments in between plumber decoration.

[meztez]

Use plumber decoration to insert comments #* or #' without any @ keyword. Simple # break the block parser.

#* Add multipart form parser
#* @parser multi
# Add rds parser
#* @parser rds
#* @param rds_file:file
#* @post /test/1
#* @png
function(rds_file) {
  plot(rds_file[[1]])
}

The block parser read from bottom to top. In this case it will start at #* @png and stop at #* @parser rds since # Add rds parser is not recognized as a Plumber decoration thus ending the block.

Should blank lines also be ignored? Similar to how roxygen2 will be greedy going upwards
